I'm desperately trying to get the PdfLZWFilter to work. When applying the
variables for the PdfFilter I'm getting the error ePdfError_ValueOutOfRange .
I've come to the conclusion after a week on this, that I'm interpreting the
arguments wrong.I'm not the best programmer in the world so sum subtlety in
response would be greatly appreciated. I just need an idea as to where I could
be going wrong here? Thanks
Basically I have a vector containing the characters which as a whole form the
compressed LZW stream.
Am I supposed to pre-determine the buffer size?
Long story short, I've declared the filter correctly.
PdfFilterFactory Factory;static std::auto_ptr<PdfFilter> myfilter;myfilter =
Factory.Create(ePdfFilter_LZWDecode);
char *outputbuffer;const char* inputbuffer[3000]; // tried this with just
const char* inputbuffer; as well and thought //that the Decode function may
just accumulate values one by one? Tried a buffer as small as 10 //too.
Naturally I've added the values to the buffer from the vector. Also tried
using streams.
pdf_long *outputlength;pdf_long buffersize = 3000; //There are 3000 characters
in the vector.
// I get this error below. Any tips as to what I'm doing
wrong.myfilter->Decode(inputbuffer,buffersize,&outputbuffer,outputlength,NULL);
